Six students from around the USA attended the Concrete Masonry Technology (CMT) at the World Center for Concrete Technology (WCCT) 12-16 October 2015.  The CMT course covers all aspects of manufacturing concrete products including raw materials (cement, water, aggregate, admixtures and pigment), aggregate sieve analysis, multi-aggregate blending and mix designs.

In addition to covering material in the classroom, students work hands-on in the Besser Vibrapac block plant to have a working understanding of all aspects of block production before returning to their facilities.  This week-long Blockmakers Workshop® is one of five courses required to obtain the Master Blockmaker® status, a certification recognized as an advanced educational achievement in the concrete products industry.

Concrete Masonry Technology will be held 29 February-4 March 2016 and 26-30 September 2016. For a full class schedule please visit WCCT's Training Opportunities. For more information on Blockmakers Workshops please call +1.989.354.1023 or email

In addition to training, the WCCT also offers Research and Testing services. The WCCT was established in 2000 and assists clients in the development of new materials and products for use in the concrete industry. Our staff works directly with clients to provide confidential research and testing from complete studies including manufacturing of products in our state-of-the-art plant to review of previous test results completed by others. The WCCT has worked with several clients to help them find a use for their concrete products waste stream as the industry moves forward with sustainable development. For more information on research and testing please call +1.989.358.7301 or email
